wakkadoo tech: How to Install RHN Satellite Server

This document will explain how to install, build, and configure a Red Hat Satellite Server. This document will also explain many of the requirements for Satellite and options for installations, channels, kickstart profiles, etc...

Section I: Installation

1. Follow the RHN Satellite Installation Guide on Redhat Portal.

2. Build VM with necessary requirements.

1. Choose Stand Alone DB vs Embedded DB (same machine)

2. For Stand Alone RHN Satellite only support Oracle 10g

3. Download the ISO Image for installing RHEL 6 from RHN

4. Download the ISO Image for RHN Satellite 5.4 from RHN

1. https://rhn.redhat.com/rhn/software/channel/downloads/

2. While still logged into the RHN website, download the Channel Content ISOs to be served by your Satellite

5. Install Red Hat Enterprise Linux and then RHN Satellite on the Satellite machine.

1. Recommended - 5gb + for OS

2. 30gb per Channel in /var/satellite

3. 12gb for DB in /rhnsat

6. Mount the RHN Satellite ISO through VMware then mount it in satellite server

1. [root@mysat /]# mount /dev/cdrom /media

2. [root@mysat media]# ./install.pl

3. * Starting the Red Hat Network Satellite installer.
* Performing pre-install checks.
* Pre-install checks complete. Beginning installation.
* RHN Registration.
RHN Username? todd.walters
RHN Password?
HTTP Proxy Hostname?
RHN Profile Name [mysat.mydom.com]?
* Checking for uninstalled prerequisites.
** Checking if yum is available ...
There are some packages from Red Hat Enterprise Linux that are not part
of the @base group that Satellite will require to be installed on this
system. The installer will try resolve the dependencies automatically.
However, you may want to install these prerequisites manually.
Do you want the installer to resolve dependencies [y/N]? y
* Applying updates.
* Installing RHN packages.

You should have the following technical documents in hand for use in roughly this order:

1. The RHN Satellite Installation Guide — This guide, which you are now reading, provides the essential steps necessary to get an RHN Satellite up and running.

2. The RHN Client Configuration Guide — This guide explains how to configure the systems to be served by an RHN Proxy Server or RHN Satellite. (This will also likely require referencing The RHN Reference Guide, which contains steps for registering and updating systems.)

3. The RHN Channel Management Guide — This guide identifies in great detail the recommended methods for building custom packages, creating custom channels, and managing private Errata.

4. The RHN Reference Guide — This guide describes how to create RHN accounts, register and update systems, and use the RHN website to its utmost potential. This guide will probably come in handy throughout the installation and configuration process.
